The composite Election Risk Index distils six independent screening signals into a single 0–100 reading. This page documents exactly how each component is computed, how they are weighted, and what the number does not say.

How signals are normalized to a common 0–100 scale before they are combined.
Weights, thresholds, and bands (Low / Moderate / High / Critical).
When the index misleads — small samples, demographic effects, lawful recount corrections.
